A knife-wielding man injured 22 children and one adult outside a primary school in central China as students were arriving for classes Friday, police said, the latest in a series of periodic rampage attacks at Chinese schools and kindergartens.

The attack in the Henan province village of Chengping happened shortly before 8 a.m., said a police officer from Guangshan county, where the village is located.
